Working principle:
According to GB/T5487 test method, the working principle of the determination of gasoline octane number is to use the internationally recognized astm-cfr test machine, under strict test conditions, with a variable compression ratio of the standard engine as a means of comparison with reference fuel as the standard.
Relying on the automatic regression technology platform, based on the rigorous mathematical model as the theoretical basis, advanced electronic measurement technology as the means, with the national standard of the test machine measurement results as the standard, targeted regression, measurement, to ensure that the accuracy of measurement in accordance with the standard.
It breaks through the problem that non-physical quantity is difficult to transfer, and realizes the transfer of quantity from CFR testing machine to qx-g measuring instrument, which is in line with relevant national standards.
The instrument is composed of high precision digital sensor, microcomputer, color touch screen and micro printer.
The signals collected by the sensor are transmitted to the input end of the microcomputer, and the measured results are transmitted to the touch screen display after being processed by the CPU.
The screen displays RON, motor MON, anti-knock index (M+R)/2, and can be stored for browsing, reading and printing.
The instrument USES the color touch screen as the display operating system, the interface is bright and soft, the font is clear, full of three-dimensional feeling, has the effect of simple and clear operation, the measuring speed is fast, the accuracy is high, the range is wide, the function is complete and so on.
Main technical features:
1. The instrument adopts innovatively developed high-precision digital sensor with strong anti-interference ability, small variation and high precision;
Reproducibility, very good repeatability.
2. The instrument is equipped with an automatic regression technology platform, which realizes the quantity transfer from the CFR testing machine specified by the national standard to the instrument, and also realizes the connection with the national standard GB/T5487.
It improves the measuring precision and enlarges the measuring range, and lays a good foundation for the users to develop the measuring items by themselves.
3. It can be combined with the traditional oil detection equipment (distillation apparatus and density meter) to input two sets of data and carry out auxiliary calculation technology platform, so as to make the determination of cetane index and cetane value of diesel oil more accurate and meet the technical requirements of GB/T386.
4, the use of color touch screen operation mode, man-machine dialogue is simple and convenient, according to the screen display can guide the user to operate the instrument correctly, greatly improve the technical content of the instrument.
5. Application of automatic valuation calibration technology, simple calibration procedure, scientific method, accurate and reliable calibration results.
Regular maintenance and calibration by users can ensure the long-term accuracy and reliability of the instrument.
6, gasoline octane number determination, a measurement can be at the same time to study the method of octane number, motor octane number and anti-knock index (one screen three);
The determination of diesel cetane number directly shows the cetane number.
The hexadecane index can be obtained by inputting the standard density and medium boiling point, and the accurate hexadecane number can be automatically derived (one screen and two displays).
7. Less oil samples are used in the measurement of this instrument, and only 150ml sample is used for each measurement;
The measurement time is short, each measurement time is only completed within 1 minute.
